It was about time (Mario Time) that Super Mario Land for the original Game Boy was revisited. The game served as the entry point into the world of portable gaming for millions, and it was an early example of the type of adventure players could expect from a handful of AA batteries. The original Game Boy system itself may have only been able to display four shades of grey, however, that never stopped players of Super Mario Land from imagining what the game would have looked like in stunning color. Now thanks to [toruzz] we no longer have to imagine, because their Super Mario Land DX ROM Hack does just that…and then some.
The Super Mario Land DX ROM hack adheres to the Game Boy Color’s 16-bit color palette, so it actually runs on real hardware. No changes to the gameplay were made and it also runs in the native 10:9 aspect ratio for the Game Boy. According to the patch readme file, it is recommended to use a legally sourced dump of the 1.0 version of Super Mario Land and utilize Lunar IPS to apply the patch. Additionally a CRC check sum is provided to ensure everyone is working from the same starting point.
Super Mario Land was a launch title for the Game Boy in 1989, but there was another handheld game system that released that year as well (the Atari Lynx). The Lynx featured a full color backlit LCD display, so it was not as if handheld game systems of the era were restricted to being monochromatic. Granted the Lynx came with a price tag nearly twice that of the Game Boy, but a transformative ROM hack such as the Super Mario Land DX one can serve almost as an alternate history. An alternate history that we all can experience now be it on a desktop or in true portable form.
To see the Super Mario Land DX ROM Hack in motion, there is the gameplay video from YouTube user Vincent Hernandez below:

We all love the look of neon signage, but the between the glassblowing equipment, gas cylinders, high voltage, and the associated skill set, it’s not practical for everyone. Luckily, these days there’s a good alternative: “neon” flexible LED strips. This is the approach [Benni] recently took in making a large logo display, and the results speak for themselves.
[Benni] sourced the strips from AliExpress. They’re 8 mm wide and can be cut to length in multiples of 4.2 cm. Inside, there are strips of RGB LEDs, making the displays that much more versatile than actual neon. Covering the LEDs is a silicone diffuser strip that completes the illusion of a neon tube. The flexibility of the strips make them easy to bend into different shapes, but also mean a solid substrate of some sort is required to make them hold their shape. In [Benni]’s case, he used a metal frame to which he glued the strips with cyanoacrylate adhesive. He used zip ties to clamp the strips in place while the glue cured, and the fact that he clipped the tails of the zip ties is a testament to his detail-oriented nature; we would probably have left them on. All of the attention payed off though because the end product looks awesome. The finishing touches are supplied by some 3D-printed bezels carrying acrylic diffuser panels and traditional LED strips for the eyes, plus a DMX LED controller.
We’ve seen [Benni]’s work before, like this slick USB rotary encoder peripheral, and like that time, there’s a video which really shows off the project. Have a look, after the jump.

Despite all the progress video game graphics have made, it is safe to say that we won’t see any decline in oldschool 8-bit games any time soon. For some it’s about nostalgia, for others it’s just a great and simple-enough first step into game development itself. For [gocivici] it was a bit of both when he built this camcorder style, one-button gaming console.
With a Raspberry Pi Zero running PICO-8 at its core, [gocivici] salvaged the viewfinder of an old camcorder for the display, and that way turned it into a whole other kind of handheld console. For full ergonomic handling, one single, thumb-operated push button serves as only control option. This of course makes it a bit challenging to re-use existing games that would require more input options, so he and some friends decided to just write a suitable game on their own with the hopes that others might follow.
Unfortunately we don’t see a lot of projects using these old camcorder viewfinders, and considering modern LCD and OLED options it’s not really that surprising, but there’s just something intriguing about these tiny CRTs. So in case you want to see more of them, have a look at this tiny Atari display, and the DIY night vision monocle from a few years back. And to keep your eyes safe and sound, [gocivici] got you covered as well.

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of LEDs. And we think it’s pretty neat.
We have to admit to being a little confused by [marciot]’s LED matrix scanner when we first stumbled upon it. From the video below we thought that the LEDs in the matrix were being used both to detect incident light and as a display. We’ve seen LEDs used as photodiodes before, so such a contraption could work, but that’s not what’s going on here. A phototransistor is wired to an Arduino Uno and positioned above a 32×32 RGB LED matrix. A scanning routine rasters over the LEDs in the matrix while the sensor watches, and then the program turns on the LEDs that the sensor saw during the scan. Positioned far above the matrix, a large disc of light results, making it look like the phototransistor is beaming light down onto the matrix. The effect is reinforced by placing something between the sensor and the matrix, which casts a virtual shadow. Used close to the LEDs the sensor acts more like a light pen.
It’s a cool effect and it looks like a fun project to throw together. Refresh time could perhaps be a bit snappier, though; maybe an ESP32 could help with that.

In this era of 4K UHD game console graphics and controllers packed full of buttons, triggers, and joysticks, it’s good to occasionally take a step back from the leading edge. Take a breath and remind ourselves that we don’t always need all those pixels and buttons to have some fun. The LedCade is a μ (micro) arcade game cabinet built by [bobricius] for just this kind of minimalist gaming.
Using just three buttons for input and an 8×8 LED matrix for output, the LedCade can nevertheless play ten different games representing classic genres of retro arcade gaming. And in a brilliant implementation of classic hardware hacking humor, a player starts their game by inserting not a monetary coin but a CR2032 coin cell battery.
Behind the screen is a piezo speaker for appropriately vintage game sounds, and an ATmega328 with Arduino code orchestrating the fun. [bobricius] is well practiced at integrating all of these components as a result of developing an earlier project, the single board game console. This time around, the printed circuit board goes beyond being the backbone, the PCB sheet is broken apart and reformed as the enclosure. With classic arcade cabinet proportions, at a far smaller scale.
If single player minimalist gaming isn’t your thing, check out this head-to-head gaming action on 8×8 LED arrays. Or if you prefer your minimalist gaming hardware to be paper-thin, put all the parts on a flexible circuit as the Arduflexboy does.
Hundreds of years from now, the story of humanity’s inevitable spread across the solar system will be a collection of engineering problems solved, some probably in heroic fashion. We’ve already tackled a lot of these problems in our first furtive steps into the wider galaxy. Our engineering solutions have taken humans to the Moon and back, but that’s as far as we’ve been able to send our fragile and precious selves.
While we figure out how to solve the problems keeping us trapped in the Earth-Moon system, we’ve sent fleets of robotic emissaries to do our exploration by proxy, to make the observations we need to frame the next set of engineering problems to be solved. But as we reach further out into the solar system and beyond, our exploration capabilities are increasingly suffering from communications bottlenecks that restrict how much data we can ship back to Earth.
We need to find a way to send vast amounts of data back as quickly as possible using as few resources as possible on both ends of the communications link. Doing so may mean turning away from traditional radio communications and going way, way up the dial and developing practical means for communicating with X-rays.

Join us Wednesday at noon Pacific time for the Marketing and Selling Hardware Hack Chat with Shawn Hymel!
It may not be every hardware hacker’s dream, but a fair number of us harbor fantasies of thinking up the Next Big Thing and kissing the day job goodbye forever. It’s an understandable dream and a laudable goal, but as they say, a goal is a dream with a plan and a deadline. What’s your plan for turning your project into a marketable product? Chances are good you don’t have one, and if you ever expect to get to your goal you’re going to need one.
Shawn Hymel is an engineer who led several marketing campaigns for Spark Fun and recently shared his thoughts on marketing with attendees of the first-ever KiCon conference in Chicago. He’ll be dropping by the Hack Chat to talk about everything you ever wanted to know about marketing your hardware projects but were afraid to ask.
Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 8 at noon Pacific time. If time zones have got you down, we have a handy time zone converter.
Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.
